SILVENT 4020-LF: a unique product with Laval nozzle that combines highly concentrated blowing force with an easily maneuverable valve construction and low sound level. Its blowing force of 100 N (22.1 lbs) is twice that of the 4015-LF. The nozzle is made of stainless steel, making it suitable for use in practically any environment where extra high blowing force is required, e.g. the paper and manufacturing industries, steel mills etc. Features adjustable blowing force that is easily adjusted to any strength between 5% and 100%.
